DETAILED DESCRIPTION

The claimed subject matter is now described with reference to the drawings, FIGS. 1-13, wherein like reference numerals are generally used to refer to like elements throughout. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the claimed subject matter. It may be evident, however, that the claimed subject matter may be practiced without these specific details. In other instances, structures and devices are shown in block diagram form in order to facilitate describing the claimed subject matter.

FIGS. 1A and 1B are component diagrams illustrating a top view of an example implementation of a bow dampener, system and/or apparatus, for a crossbow, with further reference to FIGS. 2-13. In one implementation, a bow dampener 100 comprises a frame element 102 that is configured to support a string dampening element 130. Further, the frame element 102 comprises a barrel mount 108 that is configured to selectively engage a first side of a crossbow barrel 12. As one example, the bow dampener 100 can be mounted on the side of the crossbow barrel 12 using the barrel mount 108, and when the bowstring 18 of the crossbow 10 is released, the bowstring may make contact with the string dampening element 130 supported by the frame element 102, thereby dampening (e.g., mitigating and/or dispersing) energy from the bowstring 18 (e.g., kinetic energy resulting in vibration and/or sound).

In one implementation, the bow dampener 100 can further comprise an elongated support cavity 120 defining an axis of cavity elongation 160. The elongated support cavity 120 can be engaged with a second frame end 106 of the frame element 102, where the frame element also comprises a first frame end 104, which can be engaged with the barrel mount 108. The elongated support cavity 120 can be engaged with a second frame end 106, and/or the barrel mount 108 may be engaged with the first frame end 104 by any suitable means deemed appropriate by good engineering judgment. In one implementation, the elongated support cavity 120 can be engaged to the second frame end 106 by being integrally formed therewith. Further, in one implementation, the barrel mount 108 may be engaged to the first frame end 104 by being integrally formed therewith.

In one implementation, the elongated support cavity 120 can comprise female threads that are configured to engage at least a portion of the string dampening element 130. The string dampening element 130 can comprise an elongated support shaft 132 that defines an axis of shaft elongation 170. The elongated support shaft 132 can comprise a first shaft end 134 and a second shaft end 136. In one implementation, the first shaft end 134 may be configured to engage the elongated support cavity 120.

In one implementation, the elongated support shaft 132 can comprise male threads 138 that are disposed at least at the first shaft end 134. The elongated support shaft 132 can be configured to be adjustably engaged with the elongated support cavity 120 by threaded engagement of the male threads 138 with female threads 126 disposed in the elongated support cavity 120. The elongated support shaft 132 can define an axis of shaft elongation 170 therealong. As one example, the first shaft end 134, comprising male threads 138 thereon, may be adjustably engaged with elongated support cavity 120 by threaded engagement of the male threads 138 with said female threads 126. In this example, when the elongated support shaft 132 is threadedly engaged with elongated support cavity 120, the axis of shaft elongation 170 may coincide with the axis of cavity elongation 160. The elongated support shaft 132 may be adjustably engaged with elongated support cavity 120, for example, in the sense that the threaded engagement permits an associated user to adjust the position of the elongated support shaft 132 with respect to the elongated support cavity 120 along the axis of cavity elongation 160 by screwing the elongated support shaft 132 further into or further out of the elongated support cavity 120.

Further, in one implementation, the elongated support shaft 132 can comprise a shock tip 140 that may be engaged with the second shaft end 136. The shock tip 140 can comprise any suitable elastomeric material (e.g., configured to dampen string vibration, sound, energy, etc.). As one example, the shock tip 140 comprises an elastomeric material that is configured to absorb and dissipate kinetic energy. For example, the elastomeric material may comprise any material deemed appropriate by good engineering judgment, which, in certain implementations, may comprise a soft and pliable rubber and/or synthetic rubber.

In one implementation, the shock tip 140 may be disposed at or proximate to a position that an associated bow string 18 occupies at an end of an arrow release stroke of the bow string 18, for example, such that the bow string 18 can come in contact with the shock tip 140, thereby transferring some or all of the kinetic energy from the bowstring 18 to the shock tip 140, to be absorbed and dissipated thereby. As one example, a precise positioning of the shock tip 140 may be achieved by careful adjustment of the adjustable components (e.g., elongated support shaft 132 barrel mount 108) of the bow dampener 100 by a user. In some implementations the bow dampener 100 may be useful in mitigating potential damage to the crossbow 10, for example, when a the crossbow is “dry fired,” referring to a discharging of the cocked bow string 18 without having an arrow loaded on/in the barrel 12.

With reference to FIGS. 1B-6, in one implementation, the bow dampener 100 may be configured to be selectively engaged with a second side of the crossbow barrel 12 using the barrel mount 108′. That is, for example, the frame element 102 may be achiral or chiral. As used herein “chiral” can refer to an object or system that is not identical to its mirror image. A chiral object cannot be positioned, turned, or rotated to be identical to its minor image. Chiral is sometimes referred to as “handed-ness,” in that the right hand is chiral, and the left hand is chiral. As used herein “achiral” can refer to an object or system that has similar shape and appearance as its mirror image. An achiral object may be able to be positioned, turned or rotated to be similar to its minor image.

In one implementation, the frame element 102 may be engaged with either side of the crossbow barrel 12 of the crossbow 10, for example, by engaging the barrel mount 108 with the barrel slot 14 accessible from either side of the barrel 12. As one example, as illustrated in the implementations FIGS. 1B-6, a second bow dampener 100′ can be engaged with the other side of the crossbow barrel 12, opposite bow dampener 100. In these example implementations, the frame element 102 may be is achiral and frame element 102′ may also be achiral. That is, for example, frame element 102 may be rotated to be similar to, and serve a similar function as, frame element 102′. Further, in this example, frame element 102′ may be rotated to be similar to, and serve a similar function as, frame element 102.

In these implementations, the frame elements 102, 102′ may be selectively engaged with their respective sides of the crossbow barrel 12, using their respective barrel mounts 108, 108′, which can be configured to selectively engage with the barrel slot 14 of the crossbow barrel 12. However, the barrel mount 108 may be engaged with the associated crossbow barrel 12 (e.g., any typical crossbow) by any suitable means deemed appropriate by good engineering judgment.

In one implementation, as illustrated in the example implementations of FIGS. 7-9 and 13, the barrel mount 108 can comprise a mount fastening component 110 configured to mitigate movement of said barrel mount 108 with respect to said crossbow barrel. That is, for example, the mount fastening component 110 can facilitate the selective mounting of the frame element 102 to that crossbow barrel 12, such that the frame element 102 can hold the string dampening element 130 in an appropriate position for use in dampening the bowstring 18 vibrations, without moving.

In one implementation, the mount fastening component 110 can comprise a fastening means, such as a clamping fastener 112 as illustrated in FIG. 13; a set screw 114 as illustrated in FIG. 9; and/or a slide stop 116 as illustrated in FIG. 9. As an example, a clamping fastener 112 may comprise an opening engaged with at least a portion of the side of the crossbow barrel 12, where a size of the opening is controlled by a clamping screw 154 that can be adjusted to close the opening (e.g., clamp onto) the side of the barrel 12. As another example, a set screw 114 may be inserted into an opening in the mount fastening component 110, where the set screw 114 can be adjusted to engage with (e.g., be forced against) a portion of the side of the barrel 12, such that the barrel mount 108 is thereby held in place on the barrel 12. As another example, one or more slide stops may be positioned adjacent to the barrel mount 108 and secured against the side of the barrel 12 (e.g., by another fastening means), such that the slide stop(s) 116 mitigates movement of the barrel mount 108 laterally along the side of the barrel 12.

As illustrated in FIGS. 1-4 and 8-13, the elongated support cavity 120 of the bow dampener 100 may optionally comprise a shaft fastening component 150, which can be configured to mitigate movement of the string dampening element 130 with respect to the elongated support cavity 120. In one implementation, the shaft fastening component 150 may comprise a shaft fastening means, such as a clamping screw 154, a set screw 152, and/or a set nut 156.

In some implementations, as illustrated in FIGS. 1-4, 6-8, and 10, the elongated support cavity 120, 120′ may comprise an open seam 124, 124′ that may be configured to permit the elongated support cavity 120, 120′ to vary (slightly) in size, thereby allowing a tightness of fit, with respect to the engagement of the elongated support shaft 132, 132′ therewith, to vary. In one implementation, a variation in the size of the open seam 124, 124′ may be adjusted by a clamping screw 154, 154′ that can be configured to span the open seam 124, 124′. In implementations comprising an open seam 124, 124′ spanned by a clamping screw 154, 154′, for example, a user may adjust the clamping screw 154, 154′ to widen the open seam 124, 124′, thereby loosening the fit of the elongated support shaft 132, 132′ with respect to the elongated support cavity 120, 120′ and thereby making adjustment of the elongated support shaft 132, 132′ with respect to the elongated support cavity 120, 120′ easier. In implementations comprising an open seam 124, 124′ spanned by a clamping screw 154, 154′, for example, the user may adjust the clamping screw 154, 154′ to restrict the open seam 124, 124′, thereby tightening the fit of the elongated support shaft 132, 132′ with respect to the elongated support cavity 120, 120′ and thereby make adjustment of the elongated support shaft 132, 132′ with respect to the elongated support cavity 120, 120′ difficult or clamped into place.

In some implementations, as illustrated in FIGS. 1-4, 10, and 11, the elongated support cavity 120 may comprise an aperture 122, 122′ that can be configured to accept a set screw 152, 152′. In some implementations, the aperture 122, 122′ can comprise female threads that are configured to engage male threads of an adjustable set screw 152, 152′, such that an associated user may adjust the degree to which the set screw 152, 152′ protrudes into elongated support cavity 120, 120′. For example, the adjustment may be made by threading the set screw 152, 152′ into or out of the elongated support cavity 120, 120′ (e.g., using an appropriate tool, such as a screwdriver, hex-wrench, etc.).

As one example, a degree to which the set screw 152, 152′ may protrude into the elongated support cavity 120, 120′ can affect an adjustability of a position of the elongated support shaft 132, 132′ with respect to the elongated support cavity 120, 120′. In implementations comprising a set screw 152, 152′, a user may adjust the set screw 152, 152′, causing it to protrude into the elongated support cavity 120, 120′, thereby contacting or engaging the elongated support shaft 132, 132′, and thereby making adjustment of the elongated support shaft 132, 132′ with respect to the elongated support cavity 120, 120′ difficult or even effectively set in place. Further, the user may adjust set screw 152, 152′ to cause it to retreat from the elongated support cavity 120, 120′, thereby disengaging the elongated support shaft 132, 132′, and thereby allowing an adjustment of the elongated support shaft 132, 132′ with respect to the elongated support cavity 120, 120′ to be made.

In one implementation, as illustrated in FIG. 13, one or more set nuts 156 may be threadedly engaged with the male threads 138 of the elongated support shaft 132. In one implementation, a first set nut 156 may be disposed on the elongated support shaft 132 at a first side of the elongated support cavity 120 (e.g., toward the second shaft end 136 the elongated support shaft 132), and a second set nut 156′ may be disposed on the elongated support shaft 132 at a second side of the elongated support cavity 120 (e.g., toward the first shaft end 134 of the elongated support shaft 132). As one example, one or more set nuts 156 can be tightened (e.g., using the male threads 138) against the side(s) of the elongated support cavity 120, effectively setting the elongated support shaft 132 in place with respect to the elongated support cavity 120. As another example, the one or more set nuts 156 can be loosened from the side(s) of the elongated support cavity 120, effectively loosening the elongated support shaft 132 with respect to the elongated support cavity 120, thereby allowing adjustment of the elongated support shaft 132 with respect to the elongated support cavity 120.

In some implementations, as illustrated in the example implementations of FIGS. 5-13 the bow dampener 100, 100′ may be installed in a position on the barrel 12 of the crossbow 10, such that the axis of shaft elongation 170 intersects a riser 16 of the crossbow 10. In such implementations, the elongated support shaft 132, 132′ may be positioned to directly or indirectly contact the riser 16. That is, for example, the elongated support shaft 132 may be adjusted with respect to the elongated support cavity 120 (e.g., by threading the shaft 132 into the cavity 120), such that the first end of the elongated support shaft 132 comes in contact with the riser 16. As another example, the barrel mount 108 may be engaged with the side of the crossbow barrel 12 in such a location as to allow the first end of the elongated support shaft 132 to come in contact with (e.g., or not) the riser 16.
